Ants are one of the most cosmopolitan invasive taxa: dozens of species have invaded islands and continental areas around the globe. Invasive ants continue to colonize new ecosystems having direct and indirect negative impacts on natural and managed ecosystems. Thus, in many cases, eradication is often a desirable management action. While invasive ant eradications have increased over the past 15 years, the success rate of ant eradications is low compared to other invasive species. With colleagues from CISRO Australia and University College of London, ACS reviewed ant eradications worldwide in order to assess the practice and identify knowledge gaps and challenges.
